In your climate, with lots of airborne algal spores and rain events, I would run 10% of CYA for FC. Give you more buffer.
Overnight Chlorine loss completed...showing 11 FC now (13.5 last night), it was light on, but the sun was not actually up yet. So obviously I still have some algae, the pool is much clearer, but a touch green still. I'm out of bleach, but will continue to run the sanitizer at 100% for now. Perhaps get more bleach later to hit that 20% CYA. Sound good gents?
